This course details AC circuit analysis. Topics include Phasor
representation of sinusoidal voltage, currents, impedance, power
solution of RLC circuits, frequency response and series and parallel
resonance. Three phase power transformers and Fourier analysis
of complex waveforms are introduced. The use of computer solutions
in problem solving is included.

This is the second in a sequence of two electrical circuits
courses. Success in this course requires a good working knowledge
of algebra and trigonometry, along with a thorough understanding
of the concepts presented in ET151 Circuits
1. Simply stated, this course is an AC version of Circuits
1. Combination RLC circuits are examined in great depth. Topics
include impedance, frequency response, and resonance. Three-phase
power, transformers, and Fourier analysis of complex waveforms
are introduced. If you do not already have one, purchase of
a scientific calculator that will perform simultaneous equation
solutions with complex coefficients is strongly advised. A
minimum capability of 5 unknowns is desired. Examples include
the TI-86 and TI-89. Further, smart devices will not be allowed during tests. Also, it will be helpful to bring a set
of colored pencils or pens to lecture (3 or 4 colors) because
we create numerous simultaneous waveform plots. For lab, you'll
need the standard array of goodies as used throughout this program
(breadboard, DMM, small handtools, hook-up leads, etc.) Unless
otherwise specified, all lab exercises require a technical
report due no later than one week after the exercise. Late
penalty is one letter grade for the first half week, two letter
grades for the second half week. Reports are not accepted beyond
two weeks and receive a grade of 0. Remember, plagiarism is grounds
for failure.

Week-by-week progress and assignmentsThe problem numbers are for the 12th edition of the text. If you
have another edition of the text, please note that there
are some changes in the problem numbers. The laboratory manual may
be downloaded as a doc or pdf file at the bottom of this page.

We introduce
AC concepts of time varying quantities: sinusoidal functions
and waveforms, and calculation of average and RMS value.

Reading: Last half of chapters 10 and
12, and first portion of chapter 13. Check out the Sine
Wave Notes doc.

This week we introduce AC power and complex numbers. Complex
numbers are extremely important- you can't do the remaining material
without them, so make sure that you master the concepts.

Reading: Finish chapter 14.

Problems: Do first 6 problems from Weekend
Fun Worksheet. Chapter 14: 29, 31, (The problems in the 40's
are multi-part and may take a while. You must be able
to do these. Consider it an investment in time) 41, 42, 43, 44,
45, 48, 49, 53.

Lab:Capacitive
Reactance

We now begin elementary AC network analysis in chapter 15.
The first topic is series networks.

This week we look at parallel networks and introduce series-parallel
networks.

Reading: Finish chapter 15 and start chapter
16 by week's end.

Problems: Chapter 15: 27, 33, 39. Chapter
16: 1, 5.

Lab:Series
RLC Circuits

6

We conclude with series-parallel networks and have a test.

Reading: Finish chapter 16.

Problems: Chapter 16: 9, 13.

Lab:Parallel
RLC Circuits

Our next major topic is network theorems and analysis. This
will be spread over a few weeks. This week we start with chapter
17 on methods of analysis (source conversions, dependent sources,
mesh, nodal, etc.)

We finish AC power this week and have a test. Then we begin another major topic: frequency response
and resonance. We will be working through chapter 20 and 21 concurrently.
Only a portion of chapter 21 will be examined, primarily as applications.
The first item of interest is series resonance.
